Question

Find the length of a rectangle it's perimeter is 24 cm and breadth is 5 cm​

Answer 1

Answer:

$length = ... \\ breadth = 5 \\ perimeter = 24 \\ perimeter = 2(l + b) \\ 24 = 2(l + 5) \\ 24 = 2l + 10 \\ 2l = 24 - 10 \\ 2l = 14 \\ l = 7$

Answer 2

Answer:

So the length of rectangle is 7 cm

Step-by-step explanation:

Length = x

Breadth = 5

Perimeter = 24

Let us apply Formula of perimeter of RECTANGLE

Perimeter of rectangle = 2×(Length+ Breadth)

= 24 = 2×(x + 5)

= 24 = 2x + 10

24 - 10 = 2x

14 = 2x

$\frac{14}{2 } = x$

$7 = x$

So the length of rectangle is 7 cm
